Title: An improved combined tap or cock and lock
IPC: F16K35/06
Filed: 1928-12-31
Abstract: 322,915. Mason, W. H. Dec 31, 1928. Locks, applications of. - A combined tap and lock, as shown in Fig. 2, primarily for preventing the unauthorized use of petrol in motor vehicles, comprises a rotary plug having a hollow extension formed with gaps, as shown in Figs. 3 and 7, and a sleeve, Fig. 4, having inwardly springing fingers co-operating with the gapped extension to lock the plug in position. A key handle, Fig. 6, when pushed inwards frees the plug by spreading the spring fingers and releasing them from the gaps, whereupon the key can be pressed into the gaps for the operation of the plug.

Title: Apparatus For Operating On Sheet Material by Means of a Pattern-carrying Plate
IPC: B41F27/12
Filed: 1966-08-30
Abstract: 1,155,177. Mounting plates on cylinders. HARRIS-INTERTYPE CORP. 30 Aug., 1966 [20 Sept., 1965], No. 38565/66. Heading B6C. [Also in Division B4] An apparatus for creasing and cutting cardboard blanks comprises a plate cylinder having an axially extending gap housing means for clamping the opposite edges of a creasing and cutting plate around the cylinder. The plate clamping means includes a unit having cooperating gripping portions for gripping one edge of the plate and slidably supported in the gap adjacent one side. Also included is a platetensioning mechanism for moving the unit in plate tensioning and tension-releasing directions. This mechanism has an actuating member movable between first and second positions relative to the gap. Yieldable means operatively connect this member to the clamping unit. Actuating means are provided for moving the actuating member between the first and second positions. When the member is moved from its first position towards its second position, the yieldable means moves the unit in a platetensioning direction until the plate exerts a resisting force equal in magnitude to the force exerted by the yieldable means whereupon the actuating member moves relative to the unit in opposition to the yieldable means such that the latter yieldably holds the plate under tension and in tightly wrapped engagement with the periphery of the cylinder. The apparatus shown comprises co-operating cylinders 11, 12, Fig. 1, each having mounted thereon flexible die plates 13 or 14. The plate clamping means 26 comprising clamping units are provided in the gaps 18 to grip one end of the associated plate and a plate tensioning mechanism 160 is located in each gap 18 to move the units for plate tensioning and release. An actuating member 178 forming part of the mechanism 160 is slidable toward and from the trailing gap side 22 and is associated with each clamping unit for tensioning purposes. In its first position it abuts the unit and positions the latter against the side 22. In its second position it is spaced from the unit and located adjacent the centre of the gap 18. The yielding means are in the form of springs 180, Fig. 11. The cylinder gaps 18 also incorporate means for effecting axial and circumferential adjustment of the plates 13, 14.

Title: Roof support suitable for use in mines
Inventor: MILLS JOSEPH ALEXANDER WALLACE
IPC: E21D23/00
Filed: 1961-10-30
Abstract: 972,506. Advancing roof supports. DOWTY MINING EQUIPMENT Ltd. Oct. 18, 1962 [Oct. 30, 1961], No. 38765/61. Heading E1E. A roof support positionable between a roof R and a floor F and including a surfaceengageable member 5 and a fluid-operated prop 6 which when extended, in using the support, forces the member 5 against the roof surface, means (at 11) for applying an advancing force to the member 5 and means (at 15) for reducing the force exerted by the prop 6 on the member 5 when the prop 6 is forcing the member 5 against the surface and an advancing force is applied to the member 5 (both means being associated with an hydraulic circuit as shown in Fig. 3), until the advancing force causes the member 5 to slide along the surface with the prop 6 continuing to exert a roof supporting force. The advancing means includes a fluidoperated jack 8. The prop 6 and jack 8 are so connected to a source of fluid pressure that when this fluid is supplied to the jack 8 to apply the advancing force, it is also supplied to the prop 6 to exert a force in a prop-contracting direction. One end of the prop 6 is pivotally so connected to the member 5 that it rocks about its opposite end when the member 5 slides. A roof support having four props 6 and 7 is shown in Fig. 2 in the attitude it adopts when not being advanced and is more fully described in Specification 966,034. According to the Provisional Specification a restrictor may be used instead of the valve 10 acting as a control on the pressure source.

Title: Automatic Labelling Machine
IPC: B65C1/02
Filed: 1966-08-31
Abstract: 1,155,624. Labelling-machines. METOGESELLSCHAFT OSCAR KIND m.b.H. 31 Aug., 1966 [14 Sept., 1965], No. 38789/66, Heading B8F. Self-adhesive labels 5 are automatically applied to an article (7), Fig. 2 (not shown), carried on a conveyer below the applying apparatus, when the article actuates electro -mechanical or electro-optical sensing means which rotates an electromagnet 13 having a shaft 14 to raise an arm 15 fixed to the shaft 14 and enable a dispensing arm 3 to be lowered by means of a spring 6. As the arm 15 is raised, a lever 1 pivots anticlockwise on a spindle 18 due to a roller 16 on the arm 15 moving in a slot 17 in the lever 1. A catch 20 pivoted at 73 on the lever 1 is tripped by a pin 21<SP>1</SP>, thereby causing a roller 72 to engage the lever 71 of a brake 70 and release a strip 28 carrying the labels 5. A loop of the strip 28 is formed by a hoop 27 movable with the arm 15 to draw the strip from a supply reel (not shown). This action prevents undue drag by rollers 8, 9 which withdraw the strip when the labels 5 have been taken off it. The labels are deflected from the strip on passing a pulley 11 and applied by a roller 4, each label being previously printed by a roller 31. In rising, the end 49 of the arm 15 lifts a catch 48 to bring the roller 31 up against an inking pad 51. The electromagnet 13 is de-energized when the arm 15 is fully raised, thereby causing the arm to swing down under the force of a spring 15a until it meets a stop 41. As the arm 15 falls, the catch 20 engages the pin 21<SP>1</SP> to rotate the rollers 8, 9 and cause the strip to be withdrawn a label's length. The roller 8 is controlled by a roller 23 engaging between adjacent pins 21. The end of the arm 3 adjacent its pivot 2 carries a cam 35 loaded by a spring 37; the nose (38), Fig. 4 (not shown), of the cam being urged against the lever 1 so that a constant pressure is applied to each of the labels in spite of varying article sizes. As the arm 15 descends, the lever 1 is swung down by members 16, 17 and presses on cam 35. The dispensing arm 3 is thereby caused to swing up. The dispensing arm may be adjustable in length. The electromagnet 13 may be replaced by a pneumatically-operated cylinder.
